【 摘 要 】

The paper discusses the possibility in principle of barium-strontium modifier application as a refining and gas-protective additive for welding fluxes based on silicomanganese slag for surfacing mining equipment. In the experiments the barium-strontium flux additive was used, prepared in two ways: barium-strontium modifier mixed with liquid glass and the dust of barium-strontium modifier with a fraction less than 0.2 mm. The additives were mixed at a ratio of 2-10% from weight of silicomanganese slag. It is shown that the use of a mixture of barium-strontium modifier with liquid glass as an additive is more preferable to the use of additive as a dust. It was established that the use of not more than 8% of a barium-strontium additive is optimal from the point of view of metal contamination with nonmetallic inclusions.
